• If you did take observations of positions and clock times, how accurately do you think you could determine the positions, and how accurately do you think you would know the clock times?
If I were to take data I think that it would be nearly impossible to take accurate measurements concerning distance due to the fact that with a pause of the video the screen may sometimes be a blur. This does not mean that everything is a blur, but usually one key element to measuring with accuracy is blotched. By elements of measurement I mean the ruler and watch. There is about a tenth of a second in which the watch is 3/5 covered by the piece of wood used in the experiment. There are also moments in which the pendulum covers the vision of the roll of tape. Accuracy is not available. Estimation is.
answer/question/discussion:
• How can you use observations to determine whether the tape rolling along an incline is speeding up or slowing down?
In attempting to use the ruler’s black foot marker I would assume that the half way point is about 11 inches. If I were able to accurately measure the time that it takes the roll of tape too reach the end from the half way point and subtract it from the time that it takes to reach from the beginning to the half way point and the number was greater than zero then I would say that it was speeding up and if it were less then I would assume that it was slowing down. If the outcome was zero then I would have to assume that it has reached a maximum speed
answer/question/discussion:
• How can you use your observations to determine whether the swinging pendulum is speeding up or slowing down?
I would use the same method as I used with the tape.

Your answers are very good. You might also want to think about what additional things you could determine if you had a series of several position vs. clock time observations.
